UUID(3)                          Libuuid API                         UUID(3)

NAME         top

       uuid - DCE compatible Universally Unique Identifier library

SYNOPSIS         top

       #include <uuid.h>

DESCRIPTION         top

       The UUID library is used to generate unique identifiers for objects
       that may be accessible beyond the local system.  This library
       generates UUIDs compatible with those created by the Open Software
       Foundation (OSF) Distributed Computing Environment (DCE) utility

       The UUIDs generated by this library can be reasonably expected to be
       unique within a system, and unique across all systems.  They could be
       used, for instance, to generate unique HTTP cookies across multiple
       web servers without communication between the servers, and without
       fear of a name clash.
